Yesterday in a N.Y.C. space covered in cobwebs and candy, FEED co-founders Lauren Bush and Ellen Gustafson celebrated their new Trick-or-Treat bag for HSN, which benefits UNICEF. "Each bag purchased provides a child with micro-nutrient powder for a year. It's a cute trick-or-treat bag design and even has reflectors!" Bush told us. "This is really about addressing malnutrition issues for kids under five," Gustafson explained. HSN is donating 100% of the proceeds (bags retail for $13.20) to UNICEF. Both founders dressed for the event in Lauren Piece by Lauren Bush eco-friendly designs. As for their New York Fashion Week plans? "We went to Cynthia Rowley—really fun and cute, and Carolina Herrera," Bush told us. Flat shoes keep her comfortable going from show to show. "You walk in, and there's all these women in stilettos and they're there all day! I don't know how they do it! "Bush will be live on HSN at 10PM EST September 16th and 17th to debut the FEED Trick-or-Treat Bag, which retails for $13.20.
